Epoxy-impregnated textiles in concrete - load bearing capacity and durability
A promising possibility to improve the load bearing capacity and durability of textile reinforced concrete components is the polymeric impregnation of the textile reinforcement. Alkali resistant (AR-) glass is often used as reinforcement material. However, AR-glass loses strength in alkaline environment versus time. In this paper the mechanical behavior under short-term as well as long-term loading and the durability of textiles that were impregnated with selected epoxy resins are compared to non impregnated textiles. For this purpose tensile tests on impregnated filaments, rovings and textile reinforced specimens after an accelerated aging have been carried out. The load bearing capacity of textile reinforced components is significantly increased by the use of epoxy impregnated textiles. The utilization of approx. 75 % of the material strength of the AR-glass demonstrates the ability of this reinforcement. The durability of impregnated AR-glass textiles embedded in the concrete PZ-0899-01 is improved compared to the nonimpregnated AR-glass textiles. This improvement seems to be a function of the thickness of the impregnation layer and the contact area between the alkaline (pore) solution and the reinforcement. In current research, the influence of the polymer formulation and the type of applying the coating are analysed.
